摘要：

Carbo-Iron (R) is presented as in situ reagent for dechlorination of chlorinated organic hydrocarbons in contaminated aquifers. The combination of the sorption properties of fine-grained activated carbon (AC) with the reducing properties of metallic iron extends the environmental application fields for both materials. The material combination also helps to overcome the limitations of pure nano-iron: the carrier AC has a positive influence on the particle mobility to generate broad sorption/reaction zones and increases the affinity of the reagent to non-dissolved hydrophobic pollutants.
